グ操作が得られる。Next, the effect will be explained. When the vehicle is in a normal running condition, even if both elastic bodies 12 and 13 are torsionally deformed due to forward and reverse rotation of the steering wheel 2, the transmission mechanism 17 remains inactive, and the transmission mechanism 17 remains inactive, and the transmission mechanism 17 remains in an inactive state. The small impact force and the impact force caused by the pulsation of the hydraulic oil in the power steering device are buffered by the elastic bodies 12 and 13, and when the steering wheel 2 is rotated, a large torque is generated, such as when the steering wheel 2 is rotated. When transmitting, even if both the elastic bodies 12 and 1fl are elastically bent torsionally as fulcrums of the joints 5 and 68, and their respective axes intersect to cause whirling, the projection 18
The respective gaps between the contact surfaces 19a', 19b, 20m, and 20b hardly fluctuate, and smooth steering operation can be obtained.
